Review: Perfect for AT&T BGW320-500 Bypass! - I used this iszo SFP Stick ONU to finally eliminate the AT&T BGW320-500 gateway from my setup. It was relatively easy to modify the MAC, SN, and LOID to match my original equipment. Once configured, I plugged it directly into my UniFi UCG-Fiber, and it was recognized immediately. My connection is stable, and I’m seeing full speeds without the overhead of the ISP’s gateway. If you want a cleaner rack and better control over your routing, this is the way to go. It runs a bit warm, as most SFP ONUs do, but the performance is rock solid. Also got rid of the clunky "IP passthrough" of the BWG-320 that didn't work most of the time.
Review: Supplier is very helpful - Works with verizon network and mikrotik Rb5011 router. I dont think it even needs changing of serial or anything. Supplier is very helpful and quick. I deleted my MAC and they were so quick to provide me with new one.

Super easy to setup with ATT Fiber on their GPON network. Was able to disconnect the ATT gateway and just plug this straight into my firewall.
